IcedTea software provides a harness to build the source code from http://openjdk.java.net using Free Software build tools and provides replacements for the binary plugs with code from the GNU Classpath project.

How To Build:

We have temporarily made the decision to remove the ECJ support. The

–with-icedtea option has been made default.

Now, IcedTea bootstraps against a system installed IcedTea or a previously built version of IcedTea.

For all other distributions, it is mandatory that you have another version of IcedTea built (b19 or less). The tarballs for all the releases are available here: http://icedtea.classpath.org/download/source.
